Bug 62547 – kwrite and kate 3.3.3 crash when trying to open binary files

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description crusaderky 2004-09-01 12:47:37 UTC]

They crash on start. I've tried with several PDFs (file size 7 - 35 Mb) and one RAR (file size 300kb). I could open another RAR (270kb) successfully, though.

[Comment 1 Gregorio Guidi (RETIRED) 2004-09-01 15:40:41 UTC]

I assume it is 3.3.0. Haven't you got a backtrace?

Tried running kate/kwrite fom a console to see if there are useful messages?

Tried truncating/modifying the crashing file to get the smallest case that shows the bug?

Does it happen with a very large text file?

Maybe you can attach the 300k one...

Can reproduce it. Very nice:

Anyone keen to report upstream?

[Comment 3 crusaderky 2004-09-02 06:01:19 UTC]

Created attachment 38754 [details]
A file that provokes the crash

[Comment 4 Gregorio Guidi (RETIRED) 2004-09-03 09:52:47 UTC]

Can someone confirm that this happens when reading the bogus file only with
charset ISO8859-15? And also that in general opening a binary file (a file with '\0' character inside) produces a text noticeably smaller than the 
original?

[Comment 5 crusaderky 2004-09-03 10:03:34 UTC]

ISO 8859-15: crashes
ISO 8859-1: opened, but truncated after 2-3 lines
UTF-8: correctly opened

[Comment 6 Gregorio Guidi (RETIRED) 2004-09-03 10:57:08 UTC]

reported with a possible explanation:

http://bugs.kde.org/show_bug.cgi?id=88788

[Comment 7 Caleb Tennis (RETIRED) 2004-12-08 18:13:58 UTC]

looks to be fixed in 3.3.2

[Comment 8 crusaderky 2004-12-09 22:26:58 UTC]

Not for me. As soon as I set the charset to ISO-8859-15, it crashes as usual.

[Comment 9 Gregorio Guidi (RETIRED) 2004-12-12 07:34:44 UTC]

Probably the code was not changed for the 3.3 branch, it will be fixed in kde-3.4.

[Comment 10 Gregorio Guidi (RETIRED) 2005-01-01 10:12:02 UTC]

closing.
